Thread: 303 group-bad bedding?

@Marty Henry yup looking at the next packet being flat based, preferably the 312 diameter as well and maybe even the heavier ones above 174 grains.
Not much of the old military stuff around so factory stuff it will probably be. I do have a lee load all wack a mole loader that I can have a little play with to get it better. I have been putting that off as I struggle with the patience for full on testing but it may come to that. Front aint bedded-only done the pillars.
@shooternz yup know that. Remember the horror stories back when I was a lad in the 80's and there were still a fair few 303s around. I doubt very much I'll be playing with old war stuff unless I jag a big batch. With my luck that aint happening.
Barrel already been shortened previously and did it again myself and recrowned it on the recommendations of my gunsmith from the gun club who reblued it and did the bases for me.

Have you had the barrel slugged? I have done some and I know others who have done it or had it done none I have heard of are even close to .312"
most are .314" up to .317" my cast bullets are .314" with the nose .305", go for the heavier bullets they fit into the throat better the original bullet
was a paper patched 215 gr RN later changed to a 215 gr RN FMJ finishing up with the 174 gr MKV11 the throat is still the same as the 215gr bullets
lighter bullets like the 150 gr are way to short, Norma made a 215 gr RN soft point back in the day they shot extremely well and killed deer on the spot
Hornady's 174 gr RN was nearly has good pity they are discontinued
